Question

当我尝试运行测试时，我的app.config中的测试项目出现以下错误：

Result Message: 
Test method MYTESTPROJ.Repositories.MYREPO.MY_TEST threw exception: 
System.TypeInitializationException: The type initializer for 'System.Data.Entity.Internal.AppConfig' threw an exception. ---> 
System.Configuration.ConfigurationErrorsException: Configuration system failed to initialize --->

这是我的app.config：

    <?xml version="1.0" encoding="utf-8"?>
<configuration>
  <connectionStrings>
    <add name="xxxConnection" connectionString="xxx" providerName="System.Data.EntityClient" />

    </providers>
  </entityFramework>
</configuration>

您只需在顶部添加configSections区域即可注册该部分（您可能需要更改EF版本）。

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
  </configSections>
  <connectionStrings>
    <add name="xxxConnection" connectionString="xxx" providerName="System.Data.EntityClient" />
  </connectionStrings>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.0.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
<system.data>
    <DbProviderFactories>
      <remove name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" />
      <add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description=".Net Framework Data Provider for MySQL" type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.8.3.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />
    </DbProviderFactories>
</system.data>
<entityFramework>
    <providers>
      <provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6, Version=6.8.3.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d"></provider>
    </providers>
  </entityFramework>
</configuration>

Answer 2

我在更新.net framework 4.5.2后遇到了这个问题。似乎更新的.net框架还更新了从5.x.x到6.1.2的EntityFramework版本。

但是在web.config中它仍然没有改变。它是5.0.0.0，如果我将此值更改为6.1.2以匹配NuGet包管理器中显示的EF版本。这没有任何好处。然后我扩展了我的项目References节点，右键单击EntityFramework，显示为6.0.0.0版本。使用此值而不是6.1.2，一切都开始工作。

有同样的错误，但我认为我有configSections声明...我错误地把它放在了sectionGroup而不是configSection中。

错：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <configSections>
        <section name="quartz" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0,Culture=neutral, PublicKeyToken=b77a5c561934e089" />
            <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
        <sectionGroup name="common">
            <section name="logging" type="Common.Logging.ConfigurationSectionHandler, Common.Logging" />
      <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
        </sectionGroup>
    </configSections>...

正确：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <configSections>
        <section name="quartz" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0,Culture=neutral, PublicKeyToken=b77a5c561934e089" />
            <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
        <sectionGroup name="common">
            <section name="logging" type="Common.Logging.ConfigurationSectionHandler, Common.Logging" />
        </sectionGroup>
        <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
    </configSections>
